Quad LVDS Line Driver with High-ESD Tolerance and Flow-Through Pinout

The MAX9178 quad low-voltage differential signaling (LVDS) line driver with high-ESD tolerance is ideal for applications requiring high data rates and low power with reduced noise. The MAX9178 is guaranteed to transmit data at speeds up to 400Mbps (200MHz) over controlled impedance of media of approximately 100Ω. The transmission media can be printed circuit (PC) board traces, backplanes, or cables.

The MAX9178 accepts four LVTTL/LVCMOS inputs and translates them to LVDS output signals. All inputs tolerate overshoot of VCC +1V and undershoot of -1V. The EN and active-low EN inputs are ANDed together and control the high-impedance outputs. When the device is disabled, power drops to ultra-low 12.6mW (typ). Outputs conform to the ANSI TIA/EIA-644 LVDS standard.

The MAX9178 operates from a single +3.3V supply, and is available in a 16-pin TSSOP and 16-pin thin QFN package with exposed pad. The MAX9178 is specified for operation from -40°C to +85°C.
